Orbit Project Rationale

  • Wireless testbeds motivated by:

– cost & time needed to develop experimental prototypes – need for reproducible protocol evaluations – large‐scale system studies (...emergent behavior) – growing importance of cross‐layer protocol studies – creation of communities for wireless network research

  • ORBIT: open‐access multi‐user facility for experimental

wireless networking research primarily in unlicensed bands

– ~24/7 service facility with remote access – open interfaces for flexible layer 2,3 & cross‐layer protocols – extensive measurements at PHY, MAC and Net layers – support for wide range of radio system scenarios

WINLAB ORBIT: Open Access Research Testbed for Next‐Generation

Wireless Networks

  • Proposal: Build radio grid emulator (phase I) and

field trial network (phase II)

  • Emulator used for detailed protocol evaluations in

reproducible complex radio environments

  • Field trial network for further real‐world

evaluation & application trials

Revolutionary GENI Idea:

Slices and Deep Programmability

Install the software I want throughout my network slice (into firewalls, routers, clouds, …) And keep my slice isolated from your slice, so we don’t interfere with each other

We can run many different “future internets” in parallel

“At scale” GENI prototype

Campus photo by Vonbloompasha

Enabling “at scale” experiments

  • How can we afford / build GENI at sufficient scale?

– Clearly infeasible to build research testbed “as big as the Internet” – Therefore we are “GENI‐enabling” testbeds, commercial equipment, campuses, regional and backbone networks – Students are early adopters / participants in at‐scale experiments – Key strategy for building an at‐scale suite of infrastructure

GENI-enabled campuses, students as early adopters

WiMAX

  • Exposed all controllable parameters through

API

  • Removed all default IP routing, simplified ASN

controller*

  • All switching purely based on MAC addresses
  • Implemented the datapath virtualization and

VNTS shaping mechanism in click/openvswitch for slice isolation LTE

  • Exposed all controllable

parameters through the same REST based API

  • Implemented the datapath with
  • penvswitch
  • Current development: ePC

replacement with open source (i.e. simplification/elimination of LTE control protocols)

MobilityFirst Characteristics Mobility as the norm Hybrid name based routing Direct addressability

  • f all network

principals In‐network services Expected Scenarios High levels of mobility Strict performance requirements for name resolution service Support for coexisting multiple routing algorithms Flexible service support and deployment Reliance on software Device heterogeneity

  • Mobile nature generates particular requirements for

experimentation scenarios.

  • Named oriented architecture requires coexistence of multiple

routing paradigms at ones.
